Spiral bound notebooks, like the ones with the big spiral on the top, common in sketch books, is a huge pain in the ass trying to draw all the way to the edge of the paper.

My hand always ends up bumping the spiral and jolting my lines >:(

Dear application developers, please please please stop throwing garbage into ~ we have .cache/.config/.local for a good reason, I don't need your garbage polluting my home directory making things a huge pain, thanks.

So, it seems like IDC68 for internal SCSI connections was a common thing?

But as far as I can tell only the IDC50 header was ever actually standardized for internal unshielded connections (believe me, I check)

I wonder if they took the existing external HD68 or VHDCI68 pinouts and just used those, i've not checked that bit, but I suspect they did.

@philpem I mean it is /kinda/ dsub, but it's still an IDC connector, just with a fine pitch,

Personally i've not seen any such devices but /supposedly/ they showed up on internal CD-ROM and HDD drives.

So maybe it's the same mating connector style but just crimped onto a ribbon cable :v

I fixed my cohost bot, logicbot to allow for more than one output and also fixed the bug that was causing the netlists to be reduced to pure AOI netlists, so now we have things like muxes, and XOR gates and all that good stuff,

The general gist of how it works is that it randomly picks a number of expressions to generate (1 to 4) then for each expression it randomly picks how many terms it will have.

Once that's done, it generates a LUT with that many columns and fills it out randomly.

The LUT is then converted into Algebraic Normal Form and then either expressly simplified or not.

Once that's done it generates Verilog which is cammed into Yosys with some processing, then the netlist SVG is generated from that.

Okay okay, so this made Lina grimace when I was joking about it, but.

So, you know how you can't really do a live update into a fully new kernel, because the structure and memory layout changes, but.

What if we first setup a lookaside buffer that we could /serialize/ the internal kernel structures into and write a small replacement stub.

You'd then jump to the stub which would replace the old kernel, and then poke the new kernel to deserialize the kernel structures then resume into userspace.

I wouldn't want to actually use that, but I think it would be a funny, and very high effort shitpost.

:v

I'm pretty sure that convo ended with "protobuf in kernel", lol

Imagine binutils/gcc giving you a definitive list of supported target triples :v

@azonenberg I have something like that in the pipeline! It'll even build the cross-compilers for you if it knows how! (that's the plan anyway :v, too many projects in the works)

Debating if it would be worth the trouble to put Squishy through OSHW certification or not, hmm.

@North Yeah, i'm just not entirely sure it's overall worth it, shrug

deeply embedded firmware always makes me kinda itchy,

Like, do /you/ know what the small ARM core buried deep inside your GPU die running firmware off a baked in mask-rom is /actually/ doing?

Or what about the small core inside your HDD or SSD?

Yeah, makes me itchy,

To the person on ebay selling the old acoustic coupler for 1K USD and saying it's "RARE!", you're part of the problem,
